I
n the present study, the meshless Petrov–Galerkin (MLPG) method is adopted to study the free vibration and axial buckling
characteristics of single-walled carbon nanotube (SWCNT) subject to magnetic field. In particular, a nonlocal shell model
accounting for the small scale effect is utilized. In the theoretical formulations, a variational form of the Donnell shell equations is
constructed over a local sub-domain which leads to derivation of the mass, stiffness and geometrical stiffness matrices. The resonant
frequencies and critical axial buckling loads of SWCNT are presented. The influences of boundary conditions, nonlocal parameter
and geometrical parameters on the mechanical behavior of SWCNT are investigated and discussed completely. Finally, the numerical
results based on the present study are checked by finite element method, they show excellent agreement.
